target: free target SMP list on shutdown

On SMP targets, the "target smp" command creates a list of targets
that belong to the SMP cluster. Free this list when a target gets
destroyed on shutdown. For simplicity, the complete list is free'd as
soon as the first target of the SMP cluster is destroyed instead of
individually removing targets from the list.
